Pulse oximeter

FIG. 1 is a perspective view of a pulse oximeter showing my new design;

FIG. 2 is a right side view thereof;

FIG. 3 is a front view thereof;

FIG. 4 is a rear side view thereof;

FIG. 5 is a top view thereof;

FIG. 6 is a bottom view thereof; and,

FIG. 7 is another perspective view thereof.

A left side view is omitted since the left side view is a mirror image of the right side view.

The broken lines depict portions of the pulse oximeter in which the design is embodied that form no part of the claimed design. The broken lines in FIGS. 1 and 3 show bounds of the claimed design and also form no part thereof.
